Book excerpt: Macroeconomics in Context lays out the principles of macroeconomics in a manner that is thorough, up to date, and relevant to students. Like its counterpart, Microeconomics in Context, the book is attuned to economic realities--and it has a bargain price. The in Context books offer affordability, engaging treatment of high-interest topics from sustainability to financial crisis and rising inequality, and clear, straightforward presentation of economic theory. Policy issues are presented in context--historical, institutional, social, political, and ethical--and always with reference to human well-being.
